He grabbed the second victim by her waist with both hands, sliding them down to her buttocks. She slapped his hands away but he persisted, and grabbed her dress as she walked away.
When Huzco Huaman touched the third victim's buttocks, she verbally made it clear she was not interested in him.
Judge Brandts-Giesen said the three women had given the defendant the chance to stop, "but still you persisted''.
He then "swiped'' the body of the fourth victim in an upward motion, touching her inner thighs and underwear.
When she confronted him, he punched her in the face.
When she followed him on to the street while calling the police, he struck her on the nose, causing her to fall over in pain.
Huzco Huaman was convicted and given a first warning under the three strikes law in February.
Judge Brandts-Giesen said the defendant's working holiday visa expired next week, so his ability to impose a sentence was restricted.
He sentenced him to 120 hours community work - noting that although it was unlikely to be served, it was important to show the "condemnation of the court''.
Huzco Huaman must pay $700 to the fourth victim for emotional harm, and $100 each to the other three.
